Navy Development of Low-Cost Supersonic Turbojet Engines

This paper is a review of a Naval Air Systems Command program for exploratory development of a low-cost supersonic turbine engine. Design constraints, performance requirements, estimated engine costs, and latest program results are presented. Briefly described, the engine is 14 in in diameter, 44 in in length, produces 2300 lb thrust at Mach 1.5, sea level, (approximately 1600 lb, sea level static), and is estimated to cost $7000-11,000 in production.
